To all whom it may concern. 1

Be it known that I, JOHN M. LANDFAIR, a citizen of the United States,residing at Black Lick, in the county of Indiana and a State ofPennsylvania, have invented .a new and useful VVindow-Screen, of whichthe following is a specification. j j

The present invention relates to improvements in window screens, theprimary ob-,

ject of the inventionbeing the, provision1 of an interchangeable screenadapted to be used either upon the lower or upper sash of a window, thesame being so constructed that due to the opening or closing of thesash, the screen is stretched or contracted to cover the opening, thesame being in unobstructed view when the sash is closed, there beingvprovided further means to permitvof the easy detachment of the screencarrying member from the sash so that the sash may be opened or closedwithout affecting the screen.-

A further object of the present invention is the provision of a frameopen at one side and bodily carrying ascreen roll and means whereby thescreen may be wound or unwound due to the movement of the window sash,there being provided means for attachbination and arrangement of partsand in the details of construction hereinafter described and claimed, itbeing understood that changes in 1 the precise embodiment of v theinvention herein disclosed can be made within the scope of what isclaimed without de-- parting from the spirit of the invention.

In the drawings Figure 1 is a plan view of a window frame and sashestaken from the inside and equipped with the present invention. Fig. 2 isa similar view taken from the outside Fig. 3 is a longitudinal sectional view through the frame and sashes, with the present screen devicein the posi tion it assumes when the sashes are closed. Fig. 4: is aview in elevation of the screen roller carrying device. Fig. 5 is aperspective view of the removable frame showing the relative positiontherewith of the screen carrying roll, screen and auxiliary operatingwith either one of the sashes. the case the description of one of thecomplete mechanisms will suflice forboth.

means for rotating the roll. Fig. 6 is a view illustrating the method ofattaching the screen to the roll.

Referring to the drawings, the numeral 1 designates the window framewhich is provided with the usual lower sash 2 and the upper sash 3,, thepresent device being constructed to be interchangeable for attachment toa window frame and for coiiperation As such is The two plates 4 areprovided for attachment to the opposite sides of the window frame andare provided with the inwardly projecting plates 4", which are of such athickness as to permit of the passage of one sash past the other withoutinterfering with 1 the proper manipulation of the sashes. Gonnectedacross the ends of the plates 4 is the screen carrying plate 5 which isdetachably connected to theplates 4 by means of the rivets or bolts 20.j

A sliding plate 6 is provided and at its respective ends has attachedthereto the plates 7 and the cleats 8, which coact with the extreme endsto fit astride the respective plates 4 and thus provide a guiding meansfor the sliding plate 6 vertically between the plates 4'. In order thatthe sliding plate 6 may be detachably connected to either one of therespective sashes 2 and 3 and adjacent. to the respective lower andupper rails thereof, two plates 9 are attached to the respective lowerand upper rails of the sashes and each is provided with the rightangledterminal 10 adapted to engage one edge of the plate 6, as clearly shownin Fig. 5, to cause the plate 6 to be moved toward the connecting andscreen carrying plate 5, there being formed in the plate 9, a resilienttongue 11 which provides a means for detachably connecting the plate 6between the tongue 11 and lug 10 of the plate 9, so that as either oneof the sashes is elevated or lowered the plate 6 will be carried bycleats or tongues 11. The cleats 11 may be depressed to permit of thedisengagement of the plate 6 from the sash when it is desired todisconnect the window screen from the sash and render the The slidingplate 6 is provided with the right angled apertured arms or lugs 12, inwhich are journaled for rotation the pintles or pins 13 of the metalheads 14:, each one of which is provided with the inwardly bent lugs ortangs 15 which engage and embrace the respective ends of the cylinder16. This cylinder 16, as clearly shown in Fig. 4c, is preferably made ofa large mesh screen of wire of a heavier gage than the screen 19, saidscreen 19 as clearly shown having its end 18 secured at 17 to the roller16. It will thus be seen that as either one of the respective sashes isslid to open position, that the plate 6 will be moved so that the screen19 will be unwound and thus cover the open space, as clearly shown inFig. 1 with its side edges resting flush upon the adjacent faces of theplates 1, while in order to provide a means for rotating the roll 16 inthe opposite direction when either one of the sashes is closed andconsequently roll the screen 19 upon the roll 16, the fiat tapes 22,each of approximately the same thickness as the screen 19 have theirinner ends .connected to one of the lugs 15 as at 21, Fig. 4, while theopposite end is disposed beneath the resilient plate 24 formed from thebody of the plate 4!, the bent over end 23 being positioned as shown inFig. 5, to be again engaged by the small auxiliary clamping plate 25, ofthe plate 24. By this means the tape is readily secured to or detachedfrom its respective plate 4 and. any slack may be taken care of due tothe positioning of the end 23.

From the foregoing description, taken in connection with the drawings itis evidentthat with a window screen constructed according to andembodying the present invention, the sliding plate 6 which detachablycarries the roller 16 and the screen 19 and the tape 22, is bodilycarried by the frame constituting the plates a and 5 which are readilyattached to the window frames, as

shown in Figs. 1, 2 and 3, it simply being necessary to use severalscrews for engaging the plates 1 with the adjacent sides of the windowframe, so that the plates 4 will readily fit between the meetingportions of the sashes and not interfere with the sliding movement ofsaid sashes.

The plates 9 are positioned upon the respective lower and upper rails ofthe sashes 2 and 3 so that under normal condi tions, the resilienttongue or prong 11 will retain the plate 6 in the position, as shown inFig. 5, so that the plate 6 will be moved with its respective sash andcause the unrolling or rolling of the screen 19, due to the movement ofthe sash. It is also apparent that when it is desirable to disconnectthe plate 6 so that the sash may be opened without unrolling the screen,the resilient tongues or tangs 11 may be depressed and the metal plate 6swung outwardly so that when the sash is moved open the plate 6 willremain stationary. 7

By providing the detachable fastenings 20, the plate 5 with the screen19 may be removed and as the journaling lugs or arms 12 are resilient,the roll 16 may also be removed, while the connection at 2 1-25 permitsof the ready detachment of the plates 22, thus permitting the screenedportions to be removed in the winter time leaving the plates 4 attachedto the window frame.

As shown in Fig. 6, the clamping plates 27 and 28,-bind the end of thescreen 19 to the roller 16, longitudinally of the roller, screws 29being employed to clamp the plates, the outer one of which is in thesame plane as the outer circumference of the roller 16.

What is claimed is:

1. The combination with a window frame and'a slidable sash, of a windowscreen including a frame detachably secured to the window frame andparallel to the sash, a

plate slidably mounted upon the detachable frame, a rotatable screencarrying roller carriedby said plate, a screen attached to the rollerand to the detachable frame, a tape connected to the roller and also tothe frame, the tape being wound upon the roller when the screen isunwound and vice versa, and means carried by the sash for detachablyengaging the sliding plate to cause't-he winding and unwinding of thescreen as the sash is closed and opened.

2. The combination with a'window frame and slidable sash, of a windowscreen, including a frame detachably secured to the window frame andparallel with the sash,'a

plate slidably mounted transversely of the detachable frame, a rotatablescreen carrying roller detachably carried by said plate, a screenattached to the roller and to the detachable frame, a tape connected tothe roller and also to the frame, the tape being wound upon the rollerwhen the screen is unwound, and vice versa, and a resilient catchcarried by the sash for detachably engaging the sliding plate wherebythe platejmay be detached from movement with the sash and attached tocause the roller to wind and'unwind the screen and'tape due to themovement of the sash. I

3. A rolling screen attachment for window frames and sashes including abodily removable and attachable U-shaped frame, a sliding roll carryingmember disposed adjacentone face and transversely of the terminals ofthe frame, a screen connected to said roller at one end and having theopposite end connected to the connecting-member of the frame, and twotapes, one to each'ter- 7 end of its terminal of the frame.

4. A screen roller attachment for Window sashes and frames, includingtWo parallel plates, a bridging member connected across said plates andat right angles to the respective ends thereof, a plate slidablymountedbetween the two parallel plates for movement to and from the connectingplate, a roller detachably carried by the sliding plate, a screen havingone terminal connected to the roller and the opposite terminal to theconnecting plate, two tapes, said tapes having one of their respectiveends connected to the heads of the roller, and means for detachablyclamping the opposite ends of the tapes to the extreme ends of theparallel plates.
